Amaç: Orkestra sanatçılarında afferent işitme sistemini saf ses odyometri, yüksek frekans odyometri, geçici uyarılmış otoakustik emisyon ile; efferent işitme sistemini ise medial olivokoklear kompleks supresyon testi ile incelemektir. Gereç ve Yöntem: Aynı orkestrada çalan en az 5 yıl deneyimi olan 30 sanatçı ve kontrol grubu olarak müzik icra etmeyen 30 gönüllü alınmıştır. Saf Ses Odyometri (SSO) ve yüksek frekans odyometri ile işitme eşikleri değerlendirilmiştir. Transient uyarılmış otoakustik emisyon (TEOAE) testiyle ilk olarak kontralateral akustik stimülasyon (KAS) verilmeden önce ölçümler alınmış, daha sonra 70 dB dar band gürültü ile KAS verilerek aynı anda TEOAE testiyle medial olivokoklear kompleks refleksi (MOCR) ölçülmüştür. Ortalama prova süreleri günlük 4 saat; ortam gürültüsüne maruz kalma süreleri haftada 20-35 saat arasında değişmektedir. Bulgular: SSO eşiklerine göre; orkestra çalışanlarında 16 kHz’de özellikle sol kulakta anlamlı bir eşik yükselmesi tespit edilmiştir (orkestra grubu 42,17 dB; kontrol grubu 31,83 dB). TEOAE amplitüdleri, orkestra sanatçılarında tüm frekanslarda anlamlı derecede azdır (p<0.001). Orkestra sanatçılarında kontralateral akustik stimulasyon verildiğinde; 1, 2,4 ve 8 kHz frekanslarında anlamlı olarak TEOAE emisyon değerlerinde belirgin bir azalma tespit edilmiştir (p<0,05). Orkestra sanatçılarında prova süresi arttıkça TEOAE değerlerinde azalma gözlenirken; kontralateral supresyon değerlerinde anlamlı bir farklılık olmamıştır. Sonuç: Orkestrada çalan sanatçıların işitme sistemi değerlendirilmesinde, saf ses odyometri tek başına yeterli değildir. İşitme takibinde yüksek frekans odyometri ve otoakustik emisyonun beraber kullanımının gerekli olduğu bu çalışmada vurgulanmaktadır. Orkestra sanatçılarında medial olivary kompleks refleks aktivitesinin değerlendirilmesi önemli olmakla beraber müzisyenlerin işitme takibinde medial olivary kompleks refleks aktivitesinin tek başına kullanımı ile ilgili prospektif uzun dönem çalışmalara ihtiyaç vardır.

EVALUATION OF AFFERENT and EFFERENT AUDITORY SYSTEM IN ORCHESTRA MUSICIANS

Öz

Objectives: To evaluate afferent hearing system of musicians with pure sound audiometry, high frequency audiometry, transient-evoked otoacoustic emission and to examine the efferent hearing system with medial olivocochlear complex suppression. Materials and Methods: A total of 60 people, including 30 orchestra artists and 30 control groups, were included in this study. Hearing thresholds were evaluated with Pure Tone Audiometry. TEOAE test was first measured, then contralateral acoustic stimulation (CAS) with 70 dB narrow band noise was given and measured simultaneously with TEOAE test. The average rehearsal time is 4 hours per day and varies between 20-35 hours per week. Results: A significant threshold increase in the left ear was detected at orchestral staff at 16 kHz (orchestra group 42.17 dB; control group 31.83 dB). TEOAE amplitudes were significantly lower at all frequencies in orchestra (p <0.001). When CAS was given in the group of orchestral artists; A significant decrease in TEOAE emission values was detected at frequencies of 1, 2,4 and 8 kHz (p <0.05). While the rehearsal time has been increased, TEOAE values have been decreased. There was no significant correlation between rehearsal duration and contralateral suppression values. Conclusion: In the evaluation of the hearing system of the musicians playing in the orchestra, pure tone audiometry alone is not enough and high-frequency audiometry and TEOAE is mandatory. Although it is important to evaluate medial olivary complex reflex activity in musicians, prospective long-term studies are required for the use of medial olivary complex reflex activity alone in the follow-up of hearing in musicians.
